Syracuse Silver Knights coach Tommy Tanner evaluated his roster after the team’s fourth game of the season, an assessment that was harshly reflective of the team’s 1-3 start.

The Silver Knights needed to acquire some pure, unfiltered speed, Tanner thought. Wichita forward Jamar Beasley was an example of a player who blazed that type of mold, although even the coach couldn’t foresee the quickness with which Beasley might address that issue in Syracuse.

Tanner went ahead and plucked Beasley from the Wings in a trade last week, and Beasley immediately shifted the Silver Knights’ offense into a new gear.

Beasley arrived in Syracuse at about 10 p.m. Saturday. A few hours later, on Sunday afternoon, he produced two goals and an assist in his first Silver Knights game, a win over Rochester. He also helped ignite a transition game that Tanner said led to more tap-in goals (six) than the team managed all of last season.

“We needed to change up the chemistry of the team so we can go up and down more instead of trying to get possession,” Tanner said. “It was just contagious in that game. You see it (as a teammate) and you say, OK, you know what? This is what I’m supposed to do.”

Beasley’s professorial status in the indoor game is the product of a long education. Beasley, 33, was the MISL’s rookie of the year with Kansas City in 2003 and earned MVP honors with Detroit in 2006-2007.

“I love indoor,” said Beasley, who put up 59 points for Wichita last season. “You have to use your brain a lot. It’s being at the right place at the right time. I was ready to play (when he got to Syracuse). I’ve been playing it so long.”

That dates back at least 28 years, when Henry Beasley brought a soccer ball to his Fort Wayne, Ind., home for sons Jamar, then about 5, and DaMarcus, 2, to boot around the premises. The brothers eventually took it outside, where they’d spend hours making one-on-one runs at each other.

Henry later picked up soccer highlight videos, and the two youngsters would analyze what they saw and try to copy it in the back yard.

“We never really looked at who is better. We always just played,” Jamar said. “Indoor was my thing. Outdoor was his thing.”

DaMarcus rode his budding talent to rocket past his big brother on the national scale and earn acclaim as one of the United States’ greatest players. DaMarcus is a former MLS star and has represented his country in three World Cup tournaments.

“I’ve never looked at it as a negative, or being jealous,” Jamar said of playing in his brother’s international shadow. “It’s something he worked at, being that player.”

Jamar invested in some sweat equity himself. In 1998 he became the youngest player to sign in the MLS after joining the New England Revolution as a 17-year old directly out of high school.

“It was really overwhelming, just being around those guys and learning,” Beasley said. “I was just in shock to see those guys. I came in with a (good) attitude, ready to work. Some of those guys had been playing World Cup all their lives.”

The indoor version of the game eventually became Beasley’s niche, and it’s a career he thinks he can extend several more years. The unexpected trade from Wichita, where he was slowed by a concussion earlier this season, to the Silver Knights is another career turn in the right direction, according to Beasley.

“It’s always a good thing,” he said of the swap. “Guys tend to think of it as a negative. I took it as a positive. It’s another opportunity for me to keep playing. In this business, you always have to be ready.”
